Electric arc furnace dust recycling apparatus and method
Abstract:
The present technology provides an illustrative apparatus for recycling electric arc furnace (EAF) dust and method of use related to the same. The apparatus has a heat controlling region coupled to a separation volume and includes at least one magnet and a cooling region. The heating controlling region operates at a temperature sufficient to transform at least some of the EAF dust into a mixture of gaseous zinc and one or more additional metals. The magnet separates the iron-rich material from the mixture of gaseous zinc and one or more additional metals and the cooling region condenses the gaseous zinc.
